Hi! I raise Isa Browns, and 1 particular hen likes to sneak out and roam the yard and drive way early in the morning. So when I go out to feed the chickens (keep in mind that this hen is NOT nice or very people social) she comes up to me about 6 feet away, and crouches like she is going to lay and egg. She makes a sort of popping sound also. Why in the world does she do this? And it goes on EVERY MORNING! HELP!
